Just some extra comments and tests
I tested the weighted std and avg again, with a scenario where the random generator is
starting at max=30 increments over time up to max=300 and decrement back to 30 to see how
long it takes to adjust.
2 periods of 2097152 samples seems to be enough to get close.
I think this weight is making sense for a server running over a long period of time.
But we could adjust the period based on ping interval to make sure it is matching clear
time period.
The stdev in the middle of the scenario at max 300 is accurate 86.74 in libre office
